1. Disconnect the negative battery cable.
2. Remove the console. (See CONSOLE REMOVAL/INSTALLATION.)
3. Remove the power window main switch. (See POWER WINDOW MAIN SWITCH REMOVAL/INSTALLATION.)
4. Connect the power window main switch connector.
5. Connect the negative battery cable.
6. Verify that the voltages of each of the terminals are as indicated in the terminal voltage table.
If the voltage is not as specified in the terminal voltage table (reference), inspect the parts under Inspection item(s) and related wiring harnesses.
If the system does not work normally even though the inspection items or related wiring harnesses do not have any malfunction, replace the power window main switch. (See Terminal Voltage Table (Reference).)
